Are relationships where one of the involved people are more committed, serious about the connection they found with the other person in a relationship, because this has not been considered? I don't carry around with me a list of things to consider before making decisions or getting involved. But this kind of thinking has to be a part of what you consider important to letting anyone into your life, occupy your time, be a part of your emotional and physical existence or actuality. I believe chemistry is important, but what is relationship chemistry? Is it just being excited when you first meet someone, enjoying how they look, how she stands, smile, or with women how he sounds, talks and wears that shirt or jacket. Attraction fades either fast within the first few moments or shortly into a relationship. Love at first site does exist, it is part of that chemistry. Speaking from my experience. I loved my wife at first site. I loved how she looked, in the pool fighting off some guys she knew. She came up after being held down under water and her hair was all tight and had curls and stuff. Her screams and swings...what a tiger. Compatibility comes after the first few moments of meeting. We still disagree a bit to this day of what happened when I introduced myself to her. Compatibility can also come later. I had one of my female cousins who knew her take me over her house. When I introduced myself to her she slammed the door in my face, I may have said something like can I get your phone number so we can talk. She may have said no, and not have been as rude as I am depicting it, but to get the door closed in my face left me nothing to do but believe that was interesting and rude. No compatibility there. Looking at chemistry and compatibility, have to go hand in hand. To have the chemistry is to be compatible, and to be compatible is having the chemistry. When the compatibility is gone. So is the chemistry.
